Power skiving is a new gear cutting process that has been recognized to provide a step change in the production rate achieved in the machining of high-precision internal and external involute gears. The process is based on a continuous generating meshing between the workgear and the cutting tool. Understanding of the loads applied in the cutting tool, and therefore some of the sources of tool wear, have not been thoroughly understood. This paper presents a novel model that is able to predict with high accuracy the cutting forces in the power skiving process. The model is based on a solid modelling simulation algorithm that produces high-fidelity solid bodies that are used for the calculations. The results of the model have been experimentally validated. A series of process maps are also produced to assist in the identification of the optimal machining parameters.

“…When the disc milling cutter is in position II (corresponding to the second layer of toolpath I), the cutting point with tooth profile I is C. The cutting edge of the disc milling cutter intersects at point E in the two adjacent positions, and a straight line is made through point E perpendicular to tooth profile I, with the vertical foot F. The length of the straight line EF is the residual height of the tooth surface. The calculation method adopted in [7] and [8] can obtain the tooth surface parameters of the adjacent cutting point C according to the tooth surface parameters of the initial cutting point B. According to the cutting point C, the second-level cutting toolpaths I and II and reciprocating toolpaths are obtained, and it is cycled to obtain all the cutting toolpaths of the tooth groove.…”

To solve the problem of low efficiency in digital generating machining for producing small or medium batches of helical gears, a method to improve the machining efficiency with an indexable disc milling cutter is presented in this paper. First, the mathematical model of the tooth profile and the indexable disc milling cutter are established. Second, according to the spatial free-form envelope theory, the overall planning scheme of the tool path is given; the relative position and the relative transformation matrix of the tool and tooth profile during digital generating machining using the indexable disc milling cutter are solved, the simulation cutting and actual cutting experiments are conducted, and the cutting efficiency per unit time and cutting simulation time of the two tools under the same deformation conditions is obtained through a finite element analysis experiment. The results show that the cutting efficiency of the indexable disc milling tool was 2–3 times higher than that of the end mill cutter.

The eccentric rolling transmission consists of rolling bearings mounted eccentrically on the input shaft, cooperating with cam wheels, which are mounted on the output shaft. The aim of this paper was to determine the sensitivity of the transmission to the manufacturing errors of the cam wheel. Two methods of cam wheels milling using a universal CNC machining center were proposed. The measurements of manufactured wheels were performed using a blue light 3D scanner, which allowed the determination of geometric dimensions and deviations from nominal geometry. The experimental research of the eccentric rolling transmission prototype equipped with manufactured cam wheels was conducted, measuring the torque on the gear shafts as a function of its angular position. On the basis of the obtained results, the impact of manufacturing errors on the operation of the transmission unit was examined, especially in terms of torque and efficiency. It was indicated that the machining using ball nose end mill ensures sufficient accuracy of the cam wheels.
